Filtering rules can sort email into different folders, or reject mail.
1. Go to https://ingo.cc.columbia.edu and log in.
2. Choose 'Personal AllowList' or 'Personal BlockList' or 'New Rule'.
If you create a new rule, clicking the Save button will automatically save the given rule in Ingo as well as enable it on the server.
'Personal AllowList' sends email from certain senders directly to your Inbox, skipping any rules that follow it in your list of rules. This does NOT override the systemwide filter. It only overrides your own rules that follow it in the list.
'Personal BlockList' can be used to stop email from specific senders. If you check 'Delete message completely', the message is discarded as soon as it arrives, and there is no way to get it back. If you check 'Move message to folder', the message is delivered to that folder and you can read it if you want to. If 'Personal BlockList' matches a message, rules that follow it are not applied.
'Personal BlockList' is not useful for most junk mail, because most spammers use a different sender address for each mailing. 'Personal BlockList' works when the same sender address keeps sending you mail you don't want.
'New Rule' creates many kinds of rules. You could have all mail from a list go to its own folder, or tag mail from a sender as important, or discard mail with a certain subject. You can choose whether rules that follow should also be applied.
3. If you make changes, 'Save' to save the changes.
4. Click 'Filter Rules' at the top of the screen to go back to the main page. Click the red X after the rule you want to enable. When it changes to a green check, the rule is enabled.
The order of rules matters. As messages arrive, the rules are applied in the order shown. For example, since 'Personal AllowList' skips rules that follow, if 'Vacation' follows it, senders in the 'Personal AllowList' will never get the Vacation message. Use the arrows on the right-hand side to move rules around.
